If October really is the current targeted release month, we should start hearing some more information about the game very soon, and not just in the form of rumors anymore. We would expect a lengthy preview to be released at some point as well.
Moving the game to a more heavily generated setting could be a winning move, or it could be a disaster for the franchise – there’s really no way to know until the game is ready and released, but fans certainly seem to have high hopes for it right now.
Knowing the levels of anticipation many people have for this game, we can only hope that the release goes smoothly and that everyone is happy in the end. And if this game works out and the changes in it are taken well by fans, we wouldn’t be surprised if an announcement for another sequel came in shortly after the initial release of “Persona 5”.
